The foregoing are calculated for wind ressure on plane surfaces at right angles to the direction of the wind by the formula $$P = .004\frac{B}{30}SV^2$$. $$P =$$ pressure in pounds avoirdupois; $$S =$$ surface in square feet; $$V =$$ true (or corrected) velocity in mi per hour; $$B =$$ height of barometer in inches.

Corrected velocites indicated for Robinson anemometer for above table.
